I ran a whois query that appeared in a scam email:
whois 41.203.233.134
This returns a record that says it's in Ebene Cyber City, Mauritius.
Adding "-h whois.afrinic.net" reveals that it's actually in Burkina Faso. Is
this an old version of whois? The date of the file is August 21 this year,
but the last update of the ARIN record was in 2010.
